Samsung Galaxy S7 Edge Wifi Issues

[MitkoKirchev]

Hello guys. Before everything I want to apologise if there's a thread similar to this one (I tried searching but I couldn't find any like mine). The problem is that after my phone is idle for ~1 hour the WiFi drops and if I'm on a WhatsApp call the call just stops. WiFi comes back immediately after I unlock the phone and it's really annoying. Keep WiFi on during sleep in the WiFi settings is Always (Increases battery consumption) but after ~1 hour of idle it stops again. I tried forgetting the network but it didn't work. Factory Reset didn't help either. What I noticed (tested few times) is that when the phone is charging the WiFi stays on and the calls don't drop. Is there any way to fix that? I could leave the phone charging over night but then again there are different opinions if the battery life decreases. I have a rooted Samsung Galaxy S4 and there are no such problems with it. From what I heard there are quite a lot connectivity issues with Marshmallow. Is there a fix for that one particularly? Thank you in advance.

Hello and thanks for the reply. "Smart networx switch" has always been OFF.

Try to set in phone static IP for WIFI connection. Settings> WIFI > go on network you are connected to. Keep the finger on your network until Manage Network Settings appear. Than change under IP settings from DHCP to static. Also change DNS 1 in 8.8.8.8 and DNS 2 in 8.8.4.4

I see u try to forget network, u should try also reset network settings.
